This is one of the polishes that Catrice released recently under the Modern Muse Collection. There are altogether five polishes in the collection but one isn't new, strangely. Catrice plucked it from the permanent collection and it's one that you've seen before - In The Bronx.
Rusty But Sexy is a gorgeous burnt orange. Catrice sees it as rusty, which isn't that inaccurate either.
Honestly, I haven't got anything bad to say about it. Really, I don't. It applied well and one coat can be all right (the photos that I've shown on Witoxichic are with one coat of Rusty But Sexy).
For these close-up photos though, I have two coats on. I've been wearing this polish for six days. There is tip wear for sure and some chipping but nothing major, given the time frame.
